Cellphone Does Not Power On
The Cellphone does not respond or show any sign of powering on
Faulty Power Adapter
The BLU Tank II has a micro-USB charging port located on the top of the phone. Check to make sure that the charging cable being used is the correct type. If so make sure there are no cracks or bends in the cable and that it is firmly plugged into the wall and the phone.
If the cable is properly inserted, the screen should turn on showing a battery symbol, indicating that the phone is charging. Therefore if it doesn't appear, consider replacing the charging cable.
If the cable is properly working make sure you let the device charge for at least 24 hours. If the phone powers on but does not hold a charge, then consider replacing the battery.
If the phone still does not power on, you need a battery replacement.
